Ah. As often, writing down the problem is sufficient to crack it.
@on_trait_change('scene.activated') was required for the picking code, as suggested here:
http://docs.enthought.com/mayavi/mayavi/building_applications.html
Would have been nice if the errors would have been a little more helpful in suggesting this solution, though..

Glad you figured this out. Unfortunately, it isn't easy to produce the right error messages as the real issue is that the scene is initialized with the picker and everything else only when it is activated. If you have any ideas on how we could improve the error messages, do let us know. I am closing this issue for now. Please reopen if you see an issue. Thanks.
